Poker professional Tony Smith arrives at the mansion of a reclusive billionaire to play a private game of Texas Hold'em. He finds other poker pro's -- some friends and some not -- already there, along with the billionaire's assistant who will play in his boss's place.
The prize is $50 million, but you have to sign a contract that says losers forfeit their souls. The players convince themselves it's a psychological trick to put them off their game. But one by one players eliminated vanish and meet a horrible fate, as shown on the TV in the poker room.
The devil himself is watching and the "assistant" is a demon.
Three players remain: Tony, his best friend Cowboy Jack, and the demon. Jack tries to escape, making the demon angry and leaving Jack severely injured. The demon decides Jack needs to survive to finish the game and gives him a shot of Hell's Whiskey. Instantly healed.
When the demon is eliminated Tony and Jack are disappointed it doesn't meet a terrible end like the others, until the demon points out it's down to the two of them, which means one of them will keep his soul and the money.
Jack goes all in on shit cards, leaving him drawing dead. Tony wins but asks Jack why he sacrificed himself. "I got my reasons." As Jack heads for the exit he grabs the bottle of Hell's Whiskey.
Jack finds himself on a windy street in a western town facing a gunslinger. But drinking as much of the whiskey as he can allows him to survive his "fate" by turning him into a hellish monster.
The demon tells Tony to take his money and leave, so Tony tells him he renounces his winnings and exercises the escape clause, which he knows about because he's signed a contract for his soul before. That's how he became the world's greatest poker player. And the escape clause gets him out of all contracts he signed. He'll be a shit poker player now but he gets his soul back. The demon is in a lot of trouble.
The demon finds himself in a western saloon as the creature Jack has become walks in...
